Purpose: We aimed to assess the efficacy of percutaneous tibial nerve stimulation (PTNS) for treating overactive bladder (OAB) in a Taiwanese population and to determine the optimal treatment duration. Materials and methods: We conducted a prospective study of 69 patients diagnosed with OAB who underwent PTNS therapy between March 2023 and June 2024. Patients were evaluated across varying PTNS session frequencies, with improvements in OAB symptoms assessed using the OAB symptom score and patient perception of bladder condition questionnaires. Demographic data and treatment outcomes were analyzed using SPSS version 22.0. Results: PTNS significantly improved OAB symptoms and quality of life. It reduced frequency, nocturia, urgency, and urge incontinence episodes. A significant reduction in OAB symptom score was observed after 4 sessions of PTNS ( P = 0.021), indicating symptomatic improvement. Overall, patients who completed at least 4 sessions showed the most substantial improvements. A subjective cure response rate of 65.6% was reported. No significant adverse events were recorded, and PTNS was well tolerated by the participants. Conclusion: PTNS is an effective and minimally invasive treatment for OAB, with a 4-session protocol providing significant symptom relief. This study suggests that a shorter treatment duration may offer a cost-effective and accessible option for patients with OAB.
